Genitourinary Tract Injuries • Flashcards
Genitourinary Tract Injuries: 4 big etiologies
Blunt Trauma
Penetrating Trauma
Acceleration/Deceleration Injury
Iatrogenic
blunt Genitourinary Tract trauma: often associated with ______
pelvic fractures
from a blunt trauma, Renal parenchymal tears/laceration can be of two kinds:
1.-: non-communicating (hematoma) vs.
2.- communicating (urine
extravasation, hematuria)
a blunt trauma of the ureter is ____. And can be localted at
uretero-pelvic junction
bladder can have two types of rupture:
– extraperitoneal rupture of bladder from pelvic fracture fragments
– intraperitoneal rupture of bladder from trauma and full bladder
urethra can have two types of injuries:
– posterior urethral injuries: MVCs, falls, pelvic fractures
– anterior urethral injuries: blunt trauma to perineum, straddle injuries/direct strikes
acceleration/deceleration injury affects the renal pedicle by
high mortality rate (laceration and thrombosis of renal artery, renal vein, and their branches)
GU history
- mechanism of injury
- hematuria (microscopic or gross), blood on underwear
- dysuria, urinary retention
- history of hypotension
GU Physical Exam
- abdominal pain, flank pain, CVA tenderness, upper quadrant mass, perineal lacerations
- DRE: sphincter tone, position of prostate, presence of blood
- scrotum: ecchymoses, lacerations, testicular disruption, hematomas
- bimanual exam, speculum exam
In case of a • extraperitoneal bladder rupture we will see _______
pelvic instability, suprapubic tenderness from mass of urine or
extravasated blood
In case of a intraperitoneal bladder rupture we will see ______
acute abdomen
In case of a urethral injury we will see:
perineal ecchymosis, scrotal hematoma, blood at penile meatus, high riding prostate,
pelvic fractures
GU Trauma Investigations
• urethra:
retrograde urethrography
GU Trauma Investigations • bladder:
U/A, CT scan, urethrogram ± retrograde cystoscopy ± cystogram (distended bladder + postvoid)
GU Trauma Investigations
• ureter:
retrograde ureterogram
GU Trauma Investigations • renal:
CT scan (best, if hemodynamically stable), intravenous pyelogram
Gross hematuria suggests ______injury
bladder
In the case of gross hematuria, the GU
system is investigated from_____to
_____ (i.e. urethrogram, cystogram, etc.)
distal
proximal
renal Management
minor injuries:
conservative management
◆ bedrest, hydration, analgesia, antibiotics
renal Management major injuries: admit
◆ conservative management with frequent reassessments, serial U/A ± re-imaging
◆ surgical repair (exploration, nephrectomy): hemodynamically unstable or continuing to bleed >48 h, major urine extravasation, renal pedicle injury, all penetrating wounds and major lacerations, infections, renal artery thrombosis
Ureter injury management
ureterouretostomy
extraperitoneal bladder injury management
◆ minor rupture: Foley drainage x 10-14d
◆ major rupture: surgical repair
intraperitoneal bladder injury management
drain abdomen and surgical repair
anterior urethra injury management
conservative, if cannot void, Foley or suprapubic cystostomy and antibiotics
posterior urethra injury management
suprapubic cystostomy (avoid catheterization) ± surgical repair
